AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods by utilizing magnets rather than regular plate carriers like standard microplates or other types of particles used during immunological assays. It allows quicker capture of biomarkers from complex mixtures without losing their activity due to diffusion processes along with faster response times compared to traditional tests such as Western blots. Additionally, this new method simplifies sample preparation procedures while maintaining accuracy over multiple analyte levels. Overall, these technical improvements make them more efficient at detecting small amounts of substances within body fluids (blood).

Problems solved by technology

Technics Problem: Current techniques for detecting specific changes made during chemical therapies like cytoreductive surgery cannot accurately determine how effective their treatments were against cancer cell growths due to lack of accurate measurement tools at home settings. Additionally, current testing protocols require multiple steps and lengthy processes with poor accuracy and potential errors associated with sample preparations.
